SPECIFICATION forming part of Letters 1 Application filed April 19, 1888.

atent No. 397,731, dated February 12, 1889.

Serial .No. 271,133. (No model.)

To all whom it may concern.-

Be it known that we, JAMES LAIRD and WILLIAM MENDHAM, both citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented a certain Improved Roller for Marking Designs in Artific'al Stone, of which the followingis a specific L- tion.

The object of our invention is to construct a roller for rolling designs in cement pavements or walls, said roller being made in sections and having retainers for the different sections forming the division-lines of the designs, a further object being to have the designs removable so that different designs may be placed 011 the roller, as circumstances may require.

1n the accompanying drawings, Figure 1 is a longitudinal central section. Fig. 2 is a transverse section on the line 1 2, Fig. 1. Fig. 3 is an end View. Fig. i is a detached perspective view of one of the retaining-strips. Fig. 5 is a detached view of one of the retaining-rings, and Fig. 6 is a diagram illustrating part of the pavement with a design thereon.

In laying pavements, copings, or gardenwalks of artificial stone it is desirable to ornament them, especially at the edges, with some design. This has generally been done bylaying separate tiles, and the artificial pavement is then laid between the tiles. This plan is very expensive, and is therefore not in common use; but by providing a roller on which are designs in imitation of the faces of the tiles a very pretty effect is obtained, and by making these rollers as described hereinafter we are enabled not only to make a series of designs of the same character, one after the other, but are enabled also to make a series of different designs.

Referring to the drawings, A is the body of the roller in cross-section, as shown in Fig. 2, and has two spindles, a a, formed either by projections cast on the roller, or an independent shaft may be used, as shown. These spindles are adapted to hearings in a suitable handle by which the roller is manipulated.

In the drawings the roller is shown as divided into three sections, so that three seprate designs, or three designs of the same character, may be used; but it will be evident that the surface of the roller may be of more or less sections without departing from our invention. The body of the roller is grooved at b, and in these grooves are inserted longitudi- 5 5 nal ribs B, having reduced ends 0, over which fits a screw-ring, l), which is adapted to a reduced screw-threaded portion, (7 of the body of the roller, as shown in Figs. 1 and 3. Between each of these longitudinal ribs we insert an electrotype-plate, F, having a design of a suitable character thereon. This plate has plain edges ff, as shown in Fig. 2,which are bent down into the beveled portion of the recess 1). The longitudinal ribs have tapered under sides, c 6, corresponding with the taper of the longitudinal grooves 12 in the body of the roller, and when the longitudinal ribs are in place and the screw-rings applied to each end the electrotype-plates are firmly held in position. Thus it will be seen that by merely removing the rings and ribs anew set of electrotypes can be inserted, or a change may be made-as, for instance, Where the roller is made in three sections, all the electrotypes may be the same, or two may be of the same design and one of a different design, or all three may be different, so that when the roller forms a design upon the cement the designs will either be all the same or the designs will alternate, two of the same character and one of a different character, or every third design will be the same; and it will be readily understood that when the roller has more than three sections more than this number of designs may be used.

The retaining-ribs B and the rings D form the dividing grooves between each design, as shown in Fig. 6, and in the present instance are tapered, forming tapered grooves in the cement. These rings may have different designs upon them without departing from our invention, and in some instances the roller, instead of being adapted to hold only one design longitudinally, may be so formed as to hold a series of designs longitudinally by merely making the roller of an increased width; or the designs may be made oblong in- 5 stead of square, as shown. 1 In the drawings we have shown the rings lot I screw-til readed and adapted to reduced screw threaded portions of the body of the roller; but other means of fastening may be used without departing from our invention.

"When it is desired to form only grooves in the cement for d rivewavs, floors, &c., the elec: trotype-plates may be removed from the roller necessary grooves.

\Ve claim as our invention 1. The combination, with the roller for marl;- ing designs upon cement pavements orn'alls, i of the body having longitudinal grooves therein, grooves, and detachable screw-rings adapted detachable ribs adapted to said therein, design-plates having ends adapted to said grooves, retaining-ribs for said plates, and retain in g-ri ngs adapted to the body of the rollerand to the ribs, substantially as set forth.

3. lhe combination, w ith the roller for mark- 1 ing designs npon cement pavements or walls, and the rings and ribs alone will form the 1 oil the body having longitudinal grooves therein, concave plates the ends of? which are ada 'ited to said grooves, retaihing-ribs for said to be screwed upon each end of said roller and i over the ends of the ribs, substantially as de- I scribed.

2. The combination,with the roller for inarkf ing designs upon cement pavements or walls, t of the body having hjmgitudinal grooves plates, and retainirig-rings for the ribs, said rings and ribs forming the divh'ling-lines tor the said designs, substantial l v as set forth.

In testimoi'iy whereof we have signed our names to this specification in the presenee of two suliiseribing witnesses.
